But he also mentioned that he would rather bring the other jobs up to par, instead of outright nerfing one that is doing well. And while I can agree to SCH being quite powerful, the margin isn't as vast as his statement might make you believe. Remember SCH went into SB as the worst healer, and through adjustments, regained its top spot. But as a general consensus, healer balance is pretty decent right now. In fact job balance is pretty good overall, with most gribes being circumstancial or about the overall playstyle (MCH and DRK). Players just want those minor adjustments for AST and SCH, and for WHM to feel engaging.
As far as the whole SMN/SCH split. I can see why people would like it done, but at this stage, I say just leave it. I know when HW released they indicated they had to be careful since one affects the other. But that doesnt really seem to be the case anymore, going into SB. The entirety of the class system is "unique" but for the most part it doesn't hurt anything. Instead of trying to remove it and rework a lot of quests, I think giving certain quests "locks" that require a Soulstone to unlock, is an easier and simpler solution. I mean didnt they make getting the Soulstone easier. If anything Soulstones are the oddity, you have to incorporate them into each job now. But, basically, its like when you are on a crafter and a quest will state, "requires a desciple or war/magic to undertake"
